"Boom~"

Several thunderclaps exploded in the sky above Huangshan Mountain, and before the sound fell, the gust of wind mixed with raindrops hit the ground, vividly interpreting the ruthlessness of nature.

Zuo Zhong was wearing a dark green military (separation) raincoat, leaning on a wooden stick with his right hand and holding onto a tree with his left, as he trudged through a forest southwest of the mansion.

"Let everyone try to stay away from high places and big trees!"

Looking at the continuous lightning above his head, he stopped and turned around and shouted, telling his men to be careful about lightning protection to avoid unnecessary casualties.

Folks say that snowmen eat iron when thunder strikes, and there are piles of graves when thunder strikes in winter, which means that the omen is not very good. It seems that next year's Republic of China will not be a good year.

While thinking, Zuo Zhong raised his hand to wipe the raindrops off his face, and scanned the surrounding ground with sharp eyes, trying to find traces of the campfire.

Not only him, but all the military commanders went up the mountain to join the search operation except the secret agents who protected the mansion, trying to find more clues before the evidence disappeared.

But hurriedly, the heavy rain still fell, and the rain was extremely violent. The bean-sized raindrops hit people's faces with dull pain, and the visibility did not exceed ten meters.

In the mountain city in November, the temperature remained at around ten degrees Celsius, and dropped to seven or eight degrees after the rain. The wet and cold spies were shivering from the cold, but they all gritted their teeth and insisted on continuing to search the mountain.

"kindness."

In the heavy rain, a lone tall pine tree stood in the woods and swayed with the wind. The upper part of the tree was intact, but the lower part was cut down.

Zuo Zhong replied softly, without saying anything more, the enemy has a military background, this clue is not very useful, because the mountain city now lacks everything, except soldiers.

What are the security forces near the official residence doing? There is no mobile sentry in such an important place. If this person had been arrested earlier, what happened yesterday would not have happened.

Even if the pine tree is a non-hardwood, it is not something anyone can do if you want to cut off the forearm-thick branches with a single knife. Gucci's research and judgment on the spy just now is very accurate.

"Me too."

"Old Gu, what do you think?"

"The person who set the fire was very professional. The environment here is different from the environment around the first bonfire. There are more plants. The fire trench was dug because the fire spread would affect the bombing accuracy.

See the details for the subtleties. The time window for the spy operation last night was very short. Under such an urgent situation, it is difficult to hide his own behavioral characteristics.

Zuo Zhong looked at it for a while and turned to ask his old partner, as if he wanted to test him.

"Okay, co-seat."

After thinking about it, he put the raincoat hat on his head, got up and walked out of the awning, braved the wind and rain and came to the side of the little spy who was reporting, and looked up in the direction the other party pointed.

"Report, found traces of trees felled by the enemy."

That kind of salary is high and there is no danger. It is many times better than the job of pinning your head to your belt. Alas, the intelligence industry is getting more and more difficult to mix.

Someone in the distance suddenly shouted loudly, the sound was a little blurred in the pattering rain, but Zuo Zhong who was engrossed in it heard it immediately and reacted.

Opening his mouth and letting out a cloud of white mist, Zuo Zhong tried his best to keep his eyes wide open, not to let go of any suspicious things, and at the same time to prevent slipping (separating) and falling down the mountain.

"Report, found the second trace!"

I couldn't see my fingers last night. Unless the other party is not afraid of being exposed and using a flashlight for lighting, it is impossible to accurately find the most suitable pine tree from a forest in the dark.

Without hesitation, Gu Qi pointed to the sharp excavation marks on both sides of the fire ditch and expressed his thoughts.

So excluding this uncertain factor, and through simple calculations, we can get a range, the opponent's height is between 1 meters and 58 meters. "

Zuo Zhong complained silently, and approached the pine tree to carefully observe the cross-section of the branch. It was similar to the excavation marks of the fire protection ditch, and the broken stubble was very clean, not muddy at all.

After waiting for a long time without hearing the bragging (separation) from his subordinates, Zuo Zhong was not happy, and he didn't even give flattery to the chief.

Now we know that the first bonfire is in the southeast of the mansion, the second is in the southwest, and the third bonfire can only be in the north, and the mansion is in the center of this triangle.

Gu Qi patted his head. The air defense force is also directly north of the mansion. This is certainly not a coincidence. In addition to the poisoning incident, the spy is probably hiding in the air defense force.

"The humble job is the same as you, it must be true."

The spies said in a hurry that they understood. As for whether the words were true or not, you could tell by looking at their dazed eyes.

This analysis process sounds simple, but in a complex on-site environment, it takes a certain amount of experience and courage to be able to think of it and make a decision at the first time.

"What about the tarpaulin? Cut a few bamboos and set up the tarpaulin to protect the scene, and then use the scene as the center to search for suspicious traces within a radius of 100 meters. Be quick!

Zuo Zhong, who was at the side, heard this arrangement, and added with satisfaction: "Old Gu, let them search around the air defense force. Those who can poison the army (separate) must be insiders."

Climbing a mountain with a heavy bundle of firewood on your back, if someone sees you, you won’t be able to run away. Spies will not do such stupid things, or...

Throwing the ruler to the spy, Zuo Zhong picked up the wooden stick and began to write and draw on the ground, saying a few numbers at the same time.

As the most elite intelligence force of the national government, enjoying the envious treatment of other departments, it is natural to bear the corresponding responsibilities, and the duty dictates that it cannot be retreated.

To sum up, the other party probably has a military background, has received professional civil engineering training, and has great strength. Look at this, this person's movements are very neat. "

"Huh? Why don't you talk?"

There is a saying that only seeing thieves eating meat, but not seeing thieves being beaten, although this statement is somewhat inelegant, it aptly describes the situation of the Secret Service and even the military commanders.

The cold icy rain slapped randomly on the face, Xue Zha Guqi was full of despair, if he knew how to count back then, he would have been a fart spy, wouldn't it be good to find a foreign firm to be an accountant.

In addition, notify the other teams to meet up, and use the two discovered campfire locations and the official residence as reference objects to find the third campfire in the north of the official residence. "

Seeing this, Gucci, who came over, said, and then said while gesticulating: "Assuming that the knife used by the opponent does not exceed this length, that is to say, the spy's straight arm is only about 1.8 meters."

"Doctor Ling said that the average head-to-body ratio of Asians is about 6.75, and the height-to-arm ratio is 5:2, and the Japanese are also within this range.

Looking at the overall footprint and the depth of the front and back, it can be determined that the spy did not jump or stand on tiptoe when cutting the tree, but just stood normally.

After writing a series of calculation formulas, Zuo Zhong stood up straight and wiped his hands with a handkerchief, and smiled complacently. Congratulations for not returning the math to the teacher in junior high school.

After arranging the follow-up work, the two walked under the temporary canopy, and squatted down to observe the wet ground together.

In addition to the repeated defeats of the Guo army, or the remnants of the remnant soldiers who followed the government westward on their own initiative or passively, the number of recruits and garrison troops recruited may number in the tens of 10.

At this point in the war, the Japanese will launch the final blow at any time, and there are several armies around the mountain city just for the field (separation) troops in charge of defense.

"Old Gu, you are right."

Gucci:? ? ?
Little secret agents:? ? ?
They were just stunned for a moment. How did the deputy know the height of the spy? This is an important clue for the investigation, what happened.

Finding a few Japanese spies among so many people will not be achieved overnight. It is of no practical significance to the detection of the case. It is impossible to investigate one by one.

Gu Qi arrived with a heavy left step first, and immediately issued a few orders. This old intelligence officer, who is not visible at all times, has shown the overall planning and analysis capabilities that an intelligence director should have.

Same as the first scene, what can be seen is a pile of charcoal and mud, and the surrounding area of ​​the fire site has been burned to death. The only difference is that a fire ditch was dug here.

Another little spy shouted outside.

The guides can only provide the bomber with a rough target range, but cannot provide precise guidance, so carrying out the bombing mission is a matter of luck.

Looking at the densely packed fir trees, yellow kudzu trees, and big-leaf banyan trees in front of him, Zuo Zhong frowned, and immediately realized that the spies who set the fire must have stepped on it.

Reaching out to pat the pine tree, Zuo Zhong looked at the few footprints under the tree that were not too deep. After thinking for a while, he asked someone to bring a rope. After measuring, the distance from the ground to the highest stubble was 2 meters.

"Senior seat, the person who cuts the tree is not tall. The hatchets used by the people around the mountain city will not exceed 20 centimeters at most, no matter how long they are, they will be difficult to carry."

He ran towards the other party following the sound. The yellow soil became extremely slippery after being soaked in rain. He stumbled several times along the way and stumbled to the newly discovered scene.

Moreover, judging from the width and length of the digging marks, the spies should use German-made engineering shovels. Since the army does not distribute many such shovels, we can start the investigation from this aspect.

The same is true for German engineer shovels. The Guojun indeed issued few, but lost many on the battlefield. Besides, this thing is easy to imitate, and it is not difficult for the Japanese to obtain it.

This kind of look is often seen in the Secret Service Headquarters, oh no, it is the eyes of members of the Central Committee, confused, incomprehensible, in short, they are all question marks.

"Ah? Yes, yes, you are right, deputy seat."

In this era, air force bombing guidance usually arranged light signals in a triangular pattern, as did the Japanese.

The opponent may have been in the army or have undergone military training. He is very strong, his upper body strength is greater than that of ordinary people, and he can skillfully use engineering shovels and firewood (dividing) knives.

Hearing this, Zuo Chong couldn't help but wonder why the plants were not destroyed at the first scene. Could it be that the spies brought their own combustion aids?

Zuo Chong sighed. It seems that cultural knowledge will be added to the special training in the future, and Wen (separation) blindly cannot be a qualified intelligence officer.

It just so happened that I saved a lot of professors from Jinling and Central (separated) universities last time, so I invited them to come and give counseling, and the other party should give me face.

If Gu Qi knew what he was thinking, he would probably want to die. The mathematics in university is no different from the heavenly scriptures.

At this time, a signal flare was slowly rising due to the north of the mansion, and the third bonfire was found. Deputy Director Zuo, who was worried about his subordinates, shook the water drops on his raincoat and said a few words coldly.

"Notify Wu Chunyang that we will meet in an hour."
